**JSON-RPC is deprecated**. Migrate to either [gRPC](/concepts/data-access/grpc-overview.mdx) or [GraphQL RPC](/concepts/data-access/graphql-indexer.mdx) by April 2026.

Refer to the [list of RPC or data providers](https://www.notion.so/mystenlabs/RPC-providers-offering-future-Sui-data-primitives-2466d9dcb4e980a99a36e9aafd8c17e0?source=copy_link) that have enabled gRPC on their full nodes or offer GraphQL RPC. Contact a provider directly to request access. If your RPC or data provider doesn’t yet support these data access methods, ask them to enable support or contact the Sui Foundation team on Discord, Telegram, or Slack for help.
